Technically Kelvin is an absolute scale, where there are not “degrees,” just references to “absolute zero” which is supposed to be no vibrational energy, but is not actually zero kinetic energy since there is still zero-point energy. It’s as arbitrarily chosen a reference as any other scale, and for a specific purpose. We used it often when I was in the natural sciences, but it can be just as strange to have to think in terms of adjusting for 273.15K for the misleading “freezing point of water” or 298.15K for STP, another arbitrary standard of measurement. Kelvin is no better than Rankine. And, it’s even more confusing if you think of temperature as an average energy in a system, and have to consider quantum gases with a temperature “below absolute zero.”
Annoyance in the 21st century at cultural relics and colloquial is kind of silly.

This touches on something important, which is that Celsius is based on an arbitrary pressure. It’s based on an elevation that suits the region which defined it.
